Just purchased a 1984 rabbit GTI in silver, One of the past owners installed 1 button on the dash and 3 switches semi hidden. The dash was dilled out to place the button and it has a little umbrella next to it. 2 switches are hidden behind the 3 guage cluster on the floor, one has a little snowflake and a little flame sticker on it. the other has no markings. lastly theres an on off switch drilled and mounted into the metal bracket holding the coin/ashtray compartment in place.

if you have any idea what these switches or buttons do let me know. I've tried them all and cant figure out what they do.
